Description
Technical field
The utility model relates to structure design and the applied technical field of coupling device, specifically provides a kind of engine duct pipe end extrusion molding coupling device.
Background technology
Aircraft engine duct pipe end, the particularly shaping mode of connection of the pipe end of engine thin-walled web member adopt repeatedly shaping, require very high to the level of skill of pincers worker, and labour intensity is big, and Forming Quality is unstable, and rework rate height, therefore the condemnation factor of conduit is approximately 5%. Production efficiency is low, and the work load of workman is big, and the production cycle cannot ensure.
The pipe end of conduit is connected with installation edge forming, and traditional mode of connection adopts 3 cover frocks, and points 3 times shaping, and dismounting inconvenience, Forming Quality instability, working (machining) efficiency is low, and the labour intensity of workman is big.
People urgently wish to obtain the excellent engine duct pipe end extrusion molding coupling device of a kind of technique effect.
Practical novel content
Order of the present utility model is to provide a kind of engine duct pipe end extrusion molding coupling device.
Tube stub is connected with conduit by engine duct pipe end extrusion molding coupling device, and described engine duct pipe end extrusion molding coupling device is constructed as follows: drift 1, three lobe dop 2, three lobe type head 3, fixture block 4, half arc groove 41 it is provided with in the middle part of described fixture block 4, the both sides of half arc groove 41 are respectively arranged with through-hole structure 42, tube stub is connected in half arc groove 41 of two fixture blocks 4 by through-hole structure 42 and screw, the upper end external diameter of three lobe type heads 3 is greater than the external diameter of lower end, three lobe type heads 3 insertion with tube stub pre-assembled after conduit cavity, the upper end external diameter of three lobe dops 2 is greater than the external diameter of lower end, the inner chamber entirety of three lobe dops 2 is in taper, three lobe dops 2 insert in three lobe type heads 3, the lower end of drift 1 is cone structure 11, the middle part of drift 1 is provided with groove structure 12, the cone structure 11 of drift 1 time end inserts the inner chamber of three lobe dops 2, drift 1 and three lobe dops 2 are locked by groove structure 12.
Described engine duct pipe end extrusion molding coupling device, is connected with tube stub cold moulding is extruded for solving conduit. During use, tube stub and conduit pre-assembled, with bolt by fixture block 4 gripping tube fitting, three lobe type heads 3 insert the conduit cavity after pre-assembled, then three lobe dops 2 insert three lobe type head 3 inner chambers, and during work, drift 1 inserts three lobe dop 2 inner chambers. The mode of punching press is taked to realize cold moulding squeeze flow. By tapering drift 1 punching press three lobe dop 2 repeatedly, utilize tapering drift 1 to push ahead in three lobe dops 2 slowly and evenly, thus it is beneficial to the conical surface and reduces the gap between three lobe type head 3 appearance profiles and tube wall, thus realize radial cold moulding extruding.
Pipe wall material embeds in the annular recesses of tube stub inwall, conduit viscous deformation is bigger, tube stub mainly occurs elasticity to be out of shape, after unloading, conduit, tube stub have resilience, but tube stub resilience is relatively big, thus makes conduit together with tube stub compact siro spinning technology, and the cold moulding finally realizing pipe end is extruded. The cold moulding that this device can realize conduit and tube stub is extruded, saves starting material, makes shaping to decrease twice dismounting, twice assembling, reduce frock cost, shortens the process-cycle, greatly improve working (machining) efficiency.
Described engine duct pipe end extrusion molding coupling device, not only can alleviate the labour intensity of workman, and can guarantee junction quality, greatly alleviate work load after application, reduce production cost, it is achieved conduit pipe end is formed connected to be connect.
Described engine duct pipe end extrusion molding coupling device, it is ensured that the outer diameter tolerance of conduit controls within 0.2mm, and the consistence of size can control within 0.1mm. Shaping dimensional precision and consistence all can meet service requirements. Structure is simply light and handy, with low cost, simple to operate. Reach time saving and energy saving with the use of tapering drift, there is comparatively huge economic worth and social value.
